Development Version

The stable version of ndcube will be relatively reliable. However, if you value getting the latest updates immediately over reliablility, or want to contribute to the development of ndcube, you will need to install the bleeding edge version via github. The recommended way to set up your system is to first fork the ndcube github repository to your github account and then clone your forked repo to your local machine. This setup has the advantage of being able to push any changes you make in local version to your github account. From there you can issue pull requests to have your changes merged into the main repo and thus shared with other users. You can also set up a remote between your local version and the main repo so that you can stay updated with the latest changes to ndcube. Let’s step through how to do this.

Once you’ve forked the main ndcube github repository to your github account, create a conda environment on your local machine to hold the ndcube bleeding edge version and activate that environment. Type the following into a terminal: .. code-block:: console

$ conda config –append channels conda-forge $ conda create -n ndcube-dev python sunpy hypothesis pytest-mock $ source activate ndcube-dev

Next clone the ndcube repo from your github account to a new directory. Let’s call it ndcude-git. .. code-block:: console

To install, change into the new directory and run the install script. .. code-block:: console

$ cd ndcube-git $ pip install -e .

Finally add a remote to the main repo so you can pull the latest version. .. code-block:: console

$ git remote add upstream

Then to ensure you stay up-to-date with the latest version of ndcube, regularly do: .. code-block:: console

$ git pull upstream master

To push any changes you make to your github account by doing: .. code-block:: console

$ git push origin branch-name

where branch-name is the name of the branch you’re working on. Then from your github account you can request your changes to be merged to the main repo. For more information on on git version control, github, and issuing pull requests, see SunPy’s version control guide.
